The positive rate on the number of samples tested in Ho Chi Minh City gradually decreased


Ho Chi Minh City took a total of more than 1.6 million test samples in two days September 21 and 22, detected 8,502 positive cases, accounting for 0.52%.

This data is stated in the report on the implementation of epidemic prevention and control in the area of ​​the Ho Chi Minh City Steering Committee for Covid-19 Prevention and Control, signed by Vice Chairman of the City People’s Committee Duong Anh Duc, on September 24. .

Specifically, the health sector in two days took nearly 593,000 samples in the green area, 0.19% of the samples were positive; nearly 155,000 samples of near-green areas, 0.38% of samples were positive; 185,000 yellow area samples, 0.5% positive samples; 199,000 orange samples, 0.64% positive samples and nearly 493,000 red area samples, 0.92% positive samples.

Ho Chi Minh City has deployed large-scale screening tests from August 23 to now, and has carried out 5 rounds of sampling for households depending on the risk areas.

In which, the health sector has rapidly tested antigens for all people in the “orange” and “red zones”, which have now completed 4 batches with a total of over 5.3 million samples. The rate of positive samples gradually decreased through the tests, specifically, phase 1 was 3.6%, phase 2 was 2.7%, phase 3 was 1.1%, phase 4 was 1.1%. Phase 5 is being implemented, reaching 49% of the plan, the positive sample rate is 1%. The city has directed localities to continue carrying out tests to redraw the Covid-19 map to each hamlet and neighborhood.

All representatives of households in the “green area”, “near green” and “yellow area” were deployed with a pooled sample, the positive rate also decreased markedly.

Recently, Ho Chi Minh City has mobilized 1,533 sampling teams with more than 13,800 people to conduct testing on a large scale throughout the city. On average, each team makes 300-400 samples per day. In addition, the city also allows people to self-test with the guidance and supervision of medical staff. Initially, on average, about 22.5% of households can take samples for testing themselves. Currently, most people can take samples for rapid testing by themselves.

The city has 36 testing units authorized by the Ministry of Health to confirm Covid-19, including 11 units under the central government, ministries and sectors, 22 city public health units and 3 private medical units. The total processing capacity is 30,050 sample tubes per day. In addition, the city mobilized 3 more screening laboratories with a capacity of 16,200 samples per day, and 9 mobile testing vehicles allocated by the Ministry of Health with 1,000-2,000 samples per day.

The city is continuing the strategy of rapid testing in the area until September 30, focusing on testing very high-risk and high-risk areas to immediately isolate the source of infection and treat it promptly. This strategy is implemented entirely with a single antigen rapid test. In which, the people in the red and orange areas are tested in their entirety; people in the yellow, green and near-green areas tested representative of the household.

The main method of implementation is to instruct people to take samples for testing, health workers or volunteers to quickly distribute tests to each household, monitor testing, record results, statistics and reports. Health workers or volunteers only take samples for testing when people are unable to collect samples themselves.

In addition to the existing sampling formations, the city has mobilized an additional 1,500 personnel from the volunteer forces and reinforcements of the Ministry of Defense and the Ministry of Health. Ho Chi Minh City has also proposed to the central government to support 10 million antigen rapid test kits for this test.

According to the Ho Chi Minh City Steering Committee for Covid-19 Prevention and Control, thanks to the timely support of the Central Government, the sampling speed has made a positive change, reaching a capacity of more than 1.6 million samples in two days. repeat sampling every two days can be guaranteed. In addition, encouraging and instructing people to self-collect samples has been effective, contributing significantly to speeding up testing.

“The rate of positive cases detected in high-risk areas has steadily decreased, confirming the correctness of the policy of rapid testing,” the report stated. “The organization of screening tests achieves the goal of early detection and treatment of the outbreak, limiting the spread in the community.”
